Exodus 14:24-26

Amplified Bible

²⁴ So it happened at the early morning watch [before dawn], that the Lord looked down on the army of the Egyptians through the pillar of fire and cloud and put them in a state of confusion. ²⁵ He made their chariot wheels hard to turn, and the chariots difficult to drive; so the Egyptians said, “Let us flee from Israel, for the Lord is fighting for them against the Egyptians.”

²⁶ Then the Lord said to Moses, “Stretch out your hand over the sea so that the waters may come back over the Egyptians, on their war-chariots and their charioteers.”
